In the aerospace market, there is a major push to move toward electric flight to realize a cleaner future, reduce operating expenses and produce more reliable machines. Annually, billions of dollars are spent by major airlines on fuel consumption strategies, and there is constant pressure from governments and society to find a better solution. As such, DuXion has set out to develop a highly efficient, light and compact electric propulsion unit for several aerospace applications that range from passenger aircraft to UAVs. However, to be competitive in this market, companies need to move fast and prove their ability to comply with a robust set of rules and regulations.
Ansys TurboGrid software includes novel technology that targets complete automation combined with an unprecedented level of mesh quality for even the most complex blade shapes. The desired final mesh size is defined (and, optionally, the blade boundary layer resolution), and all the other steps are performed automatically to produce a mesh of extremely high quality. Grid angles are exceptionally good, mesh sizes transition smoothly, and high aspect-ratio elements are generated in the near-wall regions to resolve these regions efficiently and capture boundary layer flows accurately.
It has taken nearly 20 years to fine-tune milk jugs and soda bottles to achieve their current weights. But the plastics and beverage industries expect that new designs hit the market as already downgauged. This can be achieved only via continuous innovation throughout the entire blow molding process, even including research in the material science phase. This paper describes how the process of virtual prototyping in blow molding can be a very effective tool to ensure that new bottle designs achieve the objective of weight reduction while still fulfilling function.
Polymers, glass, and even food and metals exhibit complex nonlinear behavior while being processed. Accurately assessing each material’s performance requires tailor-made software with appropriate material properties models, the capability to accurately capture flow domain deformations, and robust solvers. Companies throughout the world reduce manufacturing risk by employing Ansys Polyflow to optimize extrusion, thermoforming, blow molding, glass forming, fiber drawing and concrete shaping.
